Filed Apr. 20, 1959, Ser. No. 807,456 3 Claims. (Cl. 220-11) Thisinvention relates to jackets and to packages comprised of such jacketsand inner receptacles for potable liquids or solid foods.

More specifically, this invention relates to an outer heat insulatingjacket for or in combination with an inner receptacle for the liquids orsolids.

One of the objects of this invention is to make an insulating jacket forthe receptacle of a material to provide a moisture free non-slip surfacefor the fingers and hand in handling the enclosed receptacle.

Other objects are to make the jacket of inexpensive, easily fabricated,heat insulating material, thin but resilient, and adapted for easilyencapsulating a receptacle.

Still other objects of the invention are to make a package comprising,in combination, an inner receptacle for liquids or solids whose wallsare heat transmitting, and an outer heat insulating jacket which is ofthin, resilient, inexpensive material snugly embracing the walls of theinner receptacle and provided with a hinged lid or cover to gain readyaccess to the receptacle and without necessitating the stripping off ofthe jacket from the receptacle.

Yet another object of the invention is to provide a cylinder comprisedof an insulating base, a cylindrical single walled sleeve and a flatinsulating hinged top to serve as a jacket for an inner cylindrical foodor liquid containing receptacle, the cylindrical wall having an uppersection movable with the hinged top on hinging thereof, to allow foreasy application of the lip of the user to the portion of the receptacleexposed by the removed portion of the cylindrical wall.

Other objects will become apparent upon consideration of the followingspecification when read in conjunction with the accompanying drawing inwhich:

FIG. 1 is a perspective view of the package.

FIG. 2 is a vertical diametrical section of the package with the innerreceptacle in elevation and partly broken away to expose its liquidcontents, and

FIG. 3 is a top plan view of the package.

Now referring to the drawing in greater detail, the package comprises anouter enclosure or jacket and an inner container or receptacle 12. Thereceptacle may be of any shape and may be hermetically sealed. As hereillustrated, the receptacle is a cylindrical metal can, sealed by disccovers at the top and bottom and containing a beverage 14, the can andits contents having been chilled.

The jacket 10 is of a size and form to snugly encompass the can and ismade of a thin heat insulating material of the order of one-eighth ofone inch in thickness and of a material which will readily conform toand fit snugly about the inner receptacle. Preferably, the jacket ismade of thin sheet cork, the particles of which have been autogenouslybonded by application of suitable heat and pressure, as is well known inthe art of sheet cork making.

The jacket comprises an outer cylindrical wall or sleeve 16 and a discbase 18, the base being either molded with the sleeve or cementedthereto by the use of suitable adhesives or resins. The top of thejacket comprises a cover or lid 29, also in the form of a disc, to reston the upper edges of the sleeve. A tape 22 of suitable material, suchas woven fabric or leather, is cemented to the lid near its peripheryand to the adjoining sleeve portion to form a hinge for the lid. Tofacilitate tilting of the lid, a narrow pliable metal strip 24, narrowerthan the tape, is provided. One end of the strip is passed thru the tapewhere it overlies the lid and rests between the tape and lid and isthere secured in any desired manner, as by the use of cement. The freeend of the metal strip can be bent to the position indicated in thedrawing, i.e., to an angle of approximately 45 to the plane of the discand laterally of the sleeve. Hinging of the lid is therefore easilyeffected by applying ones finger to the free end of the strip andpulling that free end downwardly.

While the cylindrical wall or sleeve may be of uniform heightthroughout, it is preferred that there shall be an arcuate cut out inthe upper edge portion of the sleeve, as illustrated at 26, for apurpose to be described. Where such an arcuate cut out portion isprovided,the cover or lid may have a complementary fitting arcuateperipheral flange 28, to fill the space in the cylindrical sleeve whenthe lid is seated on the upper edge of the sleeve. This flange like allthe rest of the jacket is of the selected heat insulating material andmay be either molded with the disc lid or cemented thereto.

The jacket itself may be an article of manufacture and sale for use andreuse with like inner receptacles or may, together with an innerreceptacle, be an article of manufacture and sale with capability ofreuse of the jacket for encompassing a receptacle after the originalreceptacle had been emptied and removed from the jacket. Therefore, inuse, either the receptacle itself may be chilled or heated prior toinsertion within the heat insulating jacket, or the package may besubjected to heat or cold, if enough time is available. In either event,the package content will be well insulated. When desired to gain accessto the contents of the receptacle, the jacket lid may be tilted to openposition and the top of the can suitably punctured or removed. If thecan contents be a liquid, such as a beverage, at least one punctureshould be at the cut out portion 26 of the sleeve so that one may applyhis lips to the can sides and top when drinking therefrom.

While the jacket wall or sleeve has been illustrated as cylindrical, itis obvious that other shaped jackets could be used, depending on theshape of the inner receptacle. In all cases, the jacket should fit theouter walls of the receptacle snugly and the top and bottom lids be asclose to the top and bottom of the receptacle as possible.

Having thus described the invention, what is claimed as new is:

1. An insulating jacket for an inner receptacle adapted to contain aliquid at a temperature variant from the ambient temperature about thejacket, said jacket comprising a thin cork cylindrical sleeve with anintegral cork disc closing the bottom the the sleeve, a cork lid, a tapehinging the lid to the sleeve, and a metal strip narrower than the tapeextending through a slit along the hinge line of said tape with one endof the strip passing between the tape and lid and secured thereto bycement and the other end of the metal strip extending beyond theconfines of the tape, said jacket having a cut out portion at its upperedge and said lid being fiangeless except for a portion opposite the cutout portion of the sleeve, said portion being of a shape and sizecomplementary to the cut out portion of the sleeve to fill said cut outportion when the lid is closed, so that one may apply his lower lipdirectly to the receptacle when the lid is raised.

2. An insulating jacket for an inner receptacle adapted to contain aliquid at a temperature variant from the ambient temperature about thejacket, said jacket comprising a cylindrical sleeve with a disc closingthe bottom of the sleeve, the upper edge of the sleeve having a cut outportion, a flangeless lid except for a depending portion opposite thecut out portion of the sleeve, said de pending portion being integralwith said lid and being of a shape and size complementary to the cut outportion of the sleeve to fill said cut out portion when the lid isclosed, so that one may apply his lower lip directly to the receptaclewhen the lid is raised, and a hinge between the lid and sleeve, saidhinge being located opposite the cut out portion of the sleeve andhaving a finger piece connected with the lid, the finger piece extendinglaterally of the sleeve away from the cut out portion, to operate thelid.

'3. An insulating jacket for a beverage can, said jacket comprising acylindrical sleeve of insulating material with a disc closing the bottomof the sleeve, the upper edge of the sleeve having a cut out portion, alid having a depending portion opposite the cut out portion of thesleeve, said depending portion being integral with said lid and being ofa shape and size complementary to the cut out portion of the sleeve tofill said cut out portion when the lid is closed, so that one may applyhis lower lip directly 15 2,484,608

to the can when the lid is raised, and a strip type hinge between thelid and sleeve, said hinge being located opposite the cut out portion ofthe sleeve.
